ABSTRACT:
This invention is for a catalyst for conversion of a hydrocarbonaceous feed. The catalyst is a zeolite aluminosilicate with a silicon to aluminum molar ratio from about 70:1 to about 100:1 on which a noble metal has been deposited. The zeolite catalyst may contain other optional tetravalent and trivalent elements in the zeolite framework. The zeolite structure may be MFI, FAU, TON, MFL, VPI, MEL, AEL, AFI, MWW or MOR. The catalyst is synthesized by preparing a zeolite containing aluminum, silicon and, optionally, other elements, such as germanium, in the framework, depositing a noble metal, such as platinum, on the zeolite and calcining the zeolite. The catalyst may be used for aromatization of alkanes to aromatics. One embodiment is a MFI zeolite catalyst which may be used for the aromatization of alkanes having two to six carbon atoms per molecule to aromatics, such as benzene, toluene and xylenes.
